Abstract

An external fixation device for holding bone fragments in place includes a housing having a number of internal mounting surfaces, in which rotationally adjustable pin holders are held by individual clamping members that simultaneously clamp the pin holder and a bone pin within the pin holder. Some of the internal surfaces are arranged to hold bone pins converging in a region of convergence spaced apart from the housing. One embodiment is arranged to hold bone fragments in place within a fractured distal radius, while another embodiment includes a rounded portion shaped as an arc.
